To all whom it may concern:

[Be it'knownfth at I, CLIFFORD E'rorrns WINBY, a subject of the King ofEngland, residing at Sutton, St; Helens, in the county ofLancaster,England, have invented new and usefuluImprovements Relating toLocoinotive, Axle- Boxes, .of which th'e following is a specification. r

.QThi invention has, reference to locomotive axle-boxes, [and more,particularly to the sponge-box offs'anre, that is the gbOX which comeSunder thewjournal of the axle, and

,,11yffit$ within depen g Side P P- The spongebox in practice is tions:olfthe upper bearing; and it further relates'to such boxes which haveremovable plates or parts for obtaining access to the lubricant holdingpart, or removable lubricantboxes. A

' enerally filled with cotton Waste or, the l'lie which absorbs andholds oil, which usually passes to it fromzthe upper bearing, into whichthe lubricant is introduced.

present, in most locomotives, the wheel comesfclose'up'to the'outside ofthe axle box and sponge box; while on the inside of the bearing: a.collar orshoulder on the shaft,or the crank in the case of a drivingaxle, c omes sothat accessto this box either from the outside. or. fromthe inside is not available; andin order'to obtain access to it forinspectionflor otherwise, it isnecessary to Y'lift the locomotive-up andlower the box.

The-object of the present invention is to provide! improvements in axleboxes which will enable access to be more readily hadto theaxle journalsand sponge boxes from inside the box, without this necessity of liftingthe locomotive; and according to this inven- .40

tion this .is accomplished by. constructing the sponge-box with aremovable part uarranged. and; adapted 'as hereinafter exl g t en n 'tas plained with reference to the drawings, that itQcan beareadilytakenoff; and when: ret movedi access to the'interiorof the box, and therebyto the journalsurface is had, so that this journal [can be ,examined,and the box repacked with waste orthe like without liftdown variousparts and connections, as well as the bearing wa PI PQ a.

v In the drawings; which illustrate thisinvention, Figure l'isaninternal faceview of y teae le arinee paegeex; a- 2 is alone gitudinalsection through the box and Fig. 3 1s a plan. Figs. 4t, ,5 and 6 arecorresponding :views to. Figs. 1, 2 and 3, showing a modification; andFig, 7 shows a complete axleboxubeari f r Referring to tilie drawing, 1isthe outside wall oftheb'ox, 2 are the side walls, and 3, the insidewall, which isthe removable art referred to. These outer and inner. endwalls or parts 1,,and3-ar'e CUIFVd/(COII'G- spond lngly with the axlelIlrOOIIHQQt-lOILWll/h which the box would belused, and the edges lieclose up to the surfaceof the journal;

and in the .c aseofa driving ,axlebox, :the 1 crank'of the locomotivewill lie. close to the inner wall 3; whereas inthecase of another axle,the shoulder or collar on the inside of the journal will lie justousidethewall 3; and'thus, ordinarily, it is-im ossible to obta n accessin an way wit the journal which lies inside t esponge .box, nor-to theinterior of the box.

In .the' form shown in; Figswl to" 3, the plate 3' has down itsgside,and along its lower edge, a thin flanged; andthe lower portion 3? ofthis end wall of the box, which lies below the bottom V5, isrecessedinward, the bottom 'ofthe recess being :fiush with thesurfaceof-the sides 2; so that when the plate 3 is in position, itsouter surface is -flushcd with the general plane and surface of theinside wall 3*; and this surfacewillalso'be flush with the surface ofithe axle bearing pro er, as usual. p

ormally, the plate 3 is: attached to the box edges of the sides2, andtothe? lower: walls of 3*, and held in position v by screwed stud bolts 6which pass through the flan es 4;,- ang screw into tapped holes in thewa lls2 an 33. i.

The heads ofwthestucls (iare made :thin, so thatin the case of theapplication to a driving-axle bearingrof. the locomotive, the path ofthe crank will be clear ofthe heads. Or the screws 6 may be countersunkinto'the plate 3. 1

A thin leather or light washer or insertion 7 is provided F between theinner surface of. the flanges 4, and faces {of the bottom 5and sides 2,a ainst whiehityfits, so that when ilt 79. wh l'lpfihee sualapins arepassed,"

which; holds the sponge box up ,in' the side portions of the bearing-box proper, and against the journal.

When it sli quil' d to: garilx-ac esstt axle shaft journal, and thelnterior of a V sponge boX, the studs 6 are w1th :lr.awn,.andH

when removed the lower edge of the lower flange l is pulled away fromthe box; and when'the bottom edge of the plate 3 at the inside corner isclear of the"bottomfifthe plate 3 can be dropped out of the way, and sothe whole'of the interior of the boxand the surface of thejournalcanbefgot at. After inspection the old waste having" been removed, a freshpacking of waste or the like can be freelyintroduc'e'd, and' pressedinto'thebox, so that'it will fill the whole 6; screwed ,up ;'-'theinsertion 7 of its' interior,"and will bear on'the under side of" theshaft; and'when:the'box issuf- 20' 'ficiently packed, the plate 3 can;be lifted; up and placedin position 'again,', and the s'tuds making thenecessary liquid tightijointf v 'Ledges marked, 10'shown in FigsQ'Q' and3 may'be furnished,in the box, and flat springs l6"arranged across the'bo'ttoni and resting on these ledges at their ends,

be used. These springs would be suitably spaced apart so'jthat. when thepacking is pressedand packed into the box: when the end plate 3 is on,the springs, bein'g light,

Furthermore, this plate 3 and the con tainer,.containing the waste orlike packing is--held in pos1t1on and pressed upward toward the axlejournal by screwing up the studs 6, whereby the annular surface of theset-screws lying outside the reduced ends 6 will lift the container up,and press the packing material or waste in it onto'the surface of thejournal.
